Among the bonus material on the second disc are deleted scenes that expand the story of Episode III.
"The deleted scenes include one that fans have been waiting a long time to see, one that shows Yoda arriving on the swamp planet of Dagobah," says Jim Ward, Senior Vice President of Lucasfilm and Executive Producer of the DVD release. "George worked with Industrial Light & Magic and Producer Rick McCallum to finish most of these scenes with complete visual effects and sound design, and they bring a new perspective to the movie."
